BURNER My invention relates to improvements in burners for gas heatingstoves, this appl cation being a division of my pending applicationSerial No. 88,753, filed February 1926, which has matured into PatentNo.

1,719,994, dated July 9th, 1929.

The object of the invention is to providea burner and mixer for the fuelof a character I particularly adapted for a stove of the peculiar designset forth herein.

In the accompanying drawings:

Fig. 1 is a front elevation of a stove em,-

bodying my improvement.

Fig. 2 is a side elevation of the same. Fig. 3 is a sectional view onthe line 33 of Fig. 1. r p

Fig. 4 is a sectional view on the line of Fig. 3.

Fig. 5 is a detail plan view of the burner,

mixing chamber and mixing valve.

Referring to the drawings, 1 represents the base of the stove of curvedform.

The 1 forwardly disposed chamber 12, disposed in rear ends of this baseare connected to ver;

tical standards 2 and the forward porti on of ments.

This support consists of a curved shaped portion 5, concavo-convex incross section, an lnner projecting shelf 6, an intermediate shelf 7 anda rear cross bar 8. intermediate shelf 7 forms a support The for aseries of heat elements 9, which are known as radiants, while the shelf6 forms a support for a curved back wall 10 of fire-proof material. Thisback wall 10 has at its uppe r end an integrally formed overhangingportion 10, the forward edge of which is of curved form. The radiants 9are formed of proof material and are of a type well known in the art ofgas heating stoves. These radiants are held in position by a flange 5formed at the juncture of the portion 5 'andshelf 7 and also by a grooveformed on the under side of the portion 10, as indicated in dotted linesat 10". The fire back 10 is held in position by forming therein grooves11, which grooves engage the inner projecting edges of the standards 2as shown in Fig. 3.

As clearly shown in Figs. 3 and 4 a j acket application filed Kay 85,

plate-20 of usual form is secured to the rear facesof the uprights 2,and by reason of the particular connection of the ends of thesubstantially semi-cylindrical fire-back 10, no portion of the fire-backcontacts with the jacket plate, the space between the fire-back 10 andjacket plate 20 providing for. circulation of air therebetween so thestove maybe set close to a house wall without danger of setting fire tothe same due to theheat radiating from the fire-back, when the stove isin use.

A cap 4 of ornamental appearance'is laid on the overhanging portion 10of the fire wall, the upper end of the jacket plate 20 and on the upperends of the standards.

The curves upon which the support, back Wall, and overhanging portionare formed are such that the radiants at each end of the series arelocated on the arc of a circle of smaller radius than that of theintermediate radiants.

The burner which employ consists of a a'curvilinear directioncorresponding to that of the radiant support, arear chamber 13, twohollow arms 14 connecting the twochambers, a hollow memberv'l5 connectedat its rear end with the chamber 13, and a fuel and air mixing valve 16connected with the forward endof the member 15. Thechambers 12and 13 andthe arms 14 are preferably integrallyformed while the member 15 isbolted to the flanged open'bottom of the chamber Theburner thus formedis connected with ears 17, projecting from the rear edge of theshelf 6,and is alsofastened to the standards2 and to bosses formed on its rearside of the cross-bar 8. The chamber 12 is disposed beneath the radiantsQand is providedwith a series of nozzles 18, one 01 each radiant, whichare screwed into openings 18 in the upper wall of the chamber 12. ItWill be notedthat the passage in the member 15 divergestoward the.mixing chamber, while the passages in the members 14 con verged from thechamber 13 to the chamber 12. This allows the air and gas to enter themixing chamber in an expanded condition 'to secure a more thoroughmixture, and to be then again contracted beforeentering the 7 burnerchamber 12 to give it the proper density for eflicient combustion.

Having thus described my invention, I claim:

1. In a burner for a gas heating stove of the type which has a series.of exposed heating elements arranged in the open front of V the stovein a curvilinear series, with the elements at each end'of the seriesarranged on the arc of a circle of shorter radius than that of theintermediate elements, the combination of a burner member having achamber arranged beneath said heating elements extending in acurvilinear direction with the ends thereof each formed on the arc of acircle of shorter radius than the intermediate portion thereof toconform to the curvature of the heating elements, and a plurality ofnoz- 'zles carried by said chamber, .one :for each heating element.

2; In a burner for .a gas heating :stove of the type whichhas a seriesof exposed heating elements arranged in the open front of the stove invacurvilinear series, with the elements at each end of the series arranged.on the arc of a circle of shorter radius than that of the intermediateelements, the combination .of a

burner member consisting of a rear chamber, a forward chamber, saidforward chamber being arranged beneath said heating elements extendingin a-curvilinear direction with the ends thereof each formed on the arcof a circle of shorter radius than the intermediate portion thereof toconform to the V curvature of the heating elements, and a pair elementsarranged in the open front of the less in length than an-endlessstructure of the stove in a curvilinear series to present a convexheating surface, the combination of a arranged in a curvilineardirection'beneath said heating elements and being considerably samecurvature and having its ends closed, a pair of communicatingpassageways extending from said rear chamber to said for ward chamber, agas supply passage extending rearwardly in communication with said rearchamber, and a gas andair valve connected with said last mentionedpassageway and located adjacent the forward portion of the stove.

4. In a burner for a gas heating stove of a the type which has a seriesof exposed'heating elements arranged in the open front of the stove in acurvilinear series to present a con vex heating surface, the combinationof a burner consisting of a rear chamber, a forward chamber, saidforward chamber being arranged in a curvilinear direction beneath saidheating elements, a pair of communicatin passageways extending from saidrear chain er to said forward chamber, said passageways diverging fromsaid rear chamber tosaid forward chamber and forming communicationsbetween said chambers, each of said passageways being converged from therear chamber to the forward chamber, a fuel supply diverging passagewayleading to said rear chamber, and a gas and air valve controlling saidlast mentioned passageway and located adjacent the forward portion ofthe stove.

In testimony whereof, I have hereunto set my hand this 24th day of May,1929. Y Y JACOB M. OLINGER.
